L’Osservatore Romano announced the appointments to the Commission on the Liturgy on 26 August 1960.
Members included Bishop Joseph Malula, a former jocist chaplain from the Belgian Congo, now auxiliary bishop of Léopoldville (now Kinshasa).
The Belgian Benedictine Bernard Botte OSB, who had also worked closely with the JOC, became a consultor.
In August 1960, the Belgian Jesuit magazine, Nouvelle Revue Théologique, published a list of the members and consultors of the various preparatory commissions.
